Definitions

  • the invention concerns to the field of tapware and in particular to taps equipped with means allowing some kind of electronic report or control of the operation.
  • the invention refers to a smart tap fitting that is configured to provide status information by means of a signal receiver (SR) on the same tap or in a nearby region, or in a remote point in the last case through a Building Management System (BMS) or Supervisory Control And Data Acquisition (SCADA) system of a building.
  • SR signal receiver
  • BMS Building Management System
  • SCADA Supervisory Control And Data Acquisition
  • the invention is of particular importance to be applied in hotels, hospitals, airports and residences in order to have supervision, control and monitoring of the whole tap fittings of the installation.
  • US 4773767 discloses a thermometer for a water tap enabling the temperature of hot water or mixed hot and cold water to be read directly from the outlet of a tap or faucet or mixing tap or shower head.
  • US 5535779 discloses a water faucet, comprising: a casing for fastening to an outlet of a water supply pipe for controlling water output, a transparent zone in said casing, wherein water in said casing is visible through the transparent zone, a temperature display chip mounted within said transparent zone, and a transparent protective covering over the temperature display chip, wherein the temperature display chip is provided to detect and display the temperature of water in or passing through the casing.
  • Patent 7850323 discloses a sanitary fitting comprising a control cartridge that is arranged in a fitting housing and is connected to a water inlet and a water outlet, an actuating lever for actuating the control cartridge, and at least one light source, wherein arranged in the actuating lever is a light guiding element, the light guiding element has a light exit region at an exit from the actuating lever and a light entrance surface at the other end, and the light source arranged in the interior of the fitting housing is intended for feeding light into the light guiding element at the light entrance surface.
  • the control cartridge is designed as a mixer cartridge and has associated a temperature sensor for the service water connected to a feed unit, and the latter drives the light source in such a way that the light source generates light of a different colour as a function of the measured temperature.
  • the invention relates to a smart tap fitting that provides a complete communication system embedded into the tap fitting with all the necessary elements to provide this information and capability of operation upstream of automatized control systems and on the basis of a design of very affordable cost.
  • the invention proposes a tap fitting enabled to be coupled to any pre-existing tap, or to a new tap.
  • the tap fitting of this invention comprises an actuating lever for regulating a flow of water that is poured through a tap supply nozzle that has attached at least one position switch that is electrically feeded and provides an information signal to a signal receiver, SR, about an angle of the lever ⁇ with regard to a rest position of the lever in which the tap is in a closed state.
  • More position switches can be included in the tap fitting to provide a better angular information about several relative positions of the lever.
  • the technology used for the position switch in one preferred embodiment involves a TILT switch.
  • Other embodiments of the position switch can be implemented using a hall device, a reed device or a gyroscope device in spite of having a cost increment.
  • the signal receiver SR can include a display included in the tap fitting or attached to a support (for example, a wall) close to the tap fitting.
  • the display technology used can give information about status of the tap fitting (on or off position) and/or water temperature by means of an electronic circuit or an IC by the use of a temperature probe included in the tap body or in a cartridge attached to the tap body , so that a warning against scalding can be given.
  • This status information and/or water temperature is received by the signal receiver, SR, that in an embodiment is in a remote position with regard to a PCB included in the tap fitting , and the PCB has a communication module interacting with the SR or with a BMS system or with a SCADA system according to the stablished parametrization and configuration.
  • This communication between the SR or with the BMS system or with the SCADA system is done through a cable or a wired Ethernet communication or a power over Ethernet communication or a wireless communication.
  • the information provided to the SR, BMS or SCADA system is used to supervision and monitoring of the tap fittings of the whole installation.
  • a actuator mechanism actuated by at least one electro valve included in the tap or in the tap fitting that permits a closure or a controlled open action of the tap on dependence of the signal provided by the position switch to the Signal Receiver, SR, or from the BMS system or from the SCADA system.
  • the information provided by the display is a numerical information of the water temperature, also providing in an alternative embodiment only or additionally visual information, like icons, of the actuator electro valve in the case that is activated by the signal receiver, SR, or the BSM or the SCADA system according to the parametrization of the tap fitting. For example, if there is a period of time when the faucet is not running, i.e. if there is a configured time that the water is not flowing through the nozzle, the system can automatically activate the electro valve of the tap fitting in order to flow the water and minimize the risk of legionella. Therefore, legionella bacteria prevention can be avoided by a simply specific cleaning process.
  • the display is a simple LED or a group of LEDs
  • the information provided in a simplified and minimalistic way giving information of the hot, cold and/or warm water temperature with a color combination or a dimming of the brightness or a flashing combination and other typical manners to provide information to the user, in addition to the situation of open or close status of the tap.
  • this power supply could come from an external source like a replaceable battery or from an electrical grid or a photovoltaic or solar power cell or wind power or a fuel cell or a thermoelectric generator or a combination thereof.
  • an adjustment system for example a screw, that permits an angular regulation of the tap fitting with regard to the tap body so that the position switch providing a sure status signal to the SR, or to the BMS or to the SCADA system.
  • the tap fitting 1 comprises an actuating lever 10 for regulating a flow of water that is poured through a tap supply nozzle (not illustrated) and has attached at least one position switch 20, that is a TILT switch (see Fig. 1 ) integrated in the body of the lever 10.
  • the position switch is electrically feeded by a battery cell.
  • This position switch 20 provides information to a signal receiver, SR included in the same tap or in a near region, or in another alternative implementation conveying the signal to a BMS system, or to a SCADA system, in all the cases informing about an angle of the lever ⁇ with regard to a rest position of the lever 10 in which the tap is in a closed state.
  • the information provided by the position switch 20 is sent to the signal receiver, SR, by wire that in a possible embodiment (as depictured in the example of Fig. 1 ) could be a circuit track connecting the position switch to a communication module 40 of the PCB 25.
  • the position of the TILT sensor or position sensor will be an established one:
  • the TILT sensor must be installed just in the vertical of the pivot axis of the lever but it can be installed over the entire length of the lever or over the entire width of the lever with respect to a central point containing the pivot axis.
  • the tap fitting of this invention also can offer temperature information of the water provided by a temperature probe included in the tap body 11 or in a cartridge attached to the tap body 11 that is connected to an electronic circuit or an IC 22 of the PCB 25 providing this information to the SR, BMS or SCADA system.
  • the tap fitting includes a LCD display 23 as a user interface with the user to provide temperature and status information of the tap fitting.
  • an adjustable system allowing an angular regulation of a support of the TILT sensor.
  • This adjustable system in a possible embodiment can include a screw accessible with a manual tool to adjust it.
